It seems like just about everywhere you go these days, from coffee shops, airports, hotels and restaurants, offers wireless Internet access to their clients. Convenient? Oh yeah! But are they safe to work on? Generally, no. Most public available wireless networks are unsecured and can be a hotbed for hackers who can glean anything from usernames and passwords or even access your computer without your permission. These four tips can help you protect yourself and your computer while working on a public network.
Check the wireless network name.
Always confirm the name of the wireless network you should be connecting to. If you are unsure, check with an employee of the hotel/coffee shop, etc. Would-be hackers can set up wireless networks in public areas with names like “Public WiFi” or “Free WiFi” in an attempt to lure people into connecting to their network; if you connect to these fraudulent networks, you may open yourself to data theft or worse.
Use a virtual private network (VPN).
VPN’s are the best way to help secure your public Internet usage session. Think of a VPN an express lane over the the “highway” of the Internet that only you are allowed on. They work by creating a virtual “tunnel” through the Internet, a two way encrypted connection that allows a user access to a private network via a public one. Using a VPN helps protect your traffic from would-be prying eyes.
VPNs are most often used by companies to give their employees access to their private networks via the Internet but there are also a number of reputable personal VPN services available, including Strong VPN http://strongvpn.com/ and WiTopia – https://www.witopia.net/. The downside of personal VPN services is that they can be pricey, starting at $50/year but if you find yourself working via public wireless networks a lot, this may be well worth the investment.
If you transmitting any sensitive information — like logins/passwords, connecting to invoicing applications, etc. — always be sure to connect via a secure connection (https://). HTTPS-Everywhere is an excellent extension available for Firefox and Chrome that forces a secure connection over 1,400 popular websites.
If you have any folders that you may have set to publicly share, disable them while you are working on a public network.
Always enable your firewall when you’re working on a public network. Firewalls are designed to only allow authorized traffic in and out of your computer. For more about how to configure and enable firewalls on your computer, here’s more information at the Microsoft and Apple websites.
Do you use public wireless networks? What types of precautions do you take?
